getPath() on Desktop UI returns an empty string

[michel.eijgermans]

LS,

WinCC-OA 3.15
Windows-7 SP1

In my application i like to read some configuration settings from configfile named "config_subsystem" which is located in the \\config directory.

To resolve the path of the config file I use
string sPath = getPath(CONFIG_REL_PATH,"config_subsystem");

I checked the file is in the directory!

Running this line of code on a normal UI then then sPath gets filled with the absolute path as expected.
Running this line of code from a Desktop-UI (on the same machine) which is connected to the project then sPath stay's empty.

I can't figure out what i'm missing here!

- Do i have to do an additional settings when running a Desktop-UI which is connected to a project running on the same machine?
- Does getPath have difficulties getting filenames from the config directory?

Best regards,
Michel.

The config directory is 'protected', files in this directory by default cannot by downloaded (by getPath). You would need to add a 'httpConnect' for these files.
Or move your files to for example to the data directory.

Gertjan, thx.
Then it makes sense that Stylesheet_dark/light isn't loaded as well

[kilianvp]

just name it "stylesheet.css" and your stylesheet will work!

they bypass the security by doing

Code: Select all

httpConnect("getTouchStyleSheet", "/config/touchscreen.css", "text/plain");

in webclient_http.ctl.

If it wont work for you dont have the lastest 3.15 Patch
